When your bat makes contact with the ball your head should be facing down. Your nose should line up directly to the middle of the ball. This will give the hitter direct vision to the ball with both eyes. If you have aspirations to go to the "Show" (major leagues) you need to practice this technique.
In below picture former New York Yankee and current Seattle Mariners player Robinson Cano reveals this discipline - it does not get better than this!
If Robinson Cano stays healthy throughout his career he will someday be inducted into Baseball's Hall of Fame.
